This is the best description I have seen of the pivotal role of CCR5 in cancer. Cytodyn should have this on its website.
The CCL5/CCR5 Axis in Cancer Progression
https://www.mdpi.com/2072-6694/12/7/1765/htm
Figure 1. Involvement of the CCL5/CCR5 axis in cancer progression. (1) CCL5, secreted by tumor cells (autocrine) and by the TME (paracrine), increases tumor growth. (2) CCL5 induces collagen degradation by activating matrix metalloproteinases in macrophages and fibroblasts. (3) CCL5 increases tumor cell migration and invasion by integrin activation (adhesion) and actin polarization. (4) CCR5+ cancer cells show characteristics of cancer stem cells. (5) CCR5 expression associates with stronger repair responses to DNA damage induced by doxorubicin and γ-irradiation. (6) CCL5 secreted by tumor cells and by the TME decreases drug cytotoxic activity. (7) CCR5 engagement stimulates glucose uptake, glycolysis, pentose phosphate pathway, fatty acid synthesis, and glutamine metabolism. (
CCL5 promotes endothelial cell migration and neovessel formation, and induces the secretion of VEGF by endothelial cells. (9) CCL5 secreted by tumor cells recruits normal cells to build the TME. (10) CCL5 induces the immunosuppressive polarization of monocytes and myeloid cells leading to M2-TAMs and MDSCs that induce exhaustion of effector T-cells.
